The Health Experts onLine at Portsmouth (HELP) system: One-year review of adult and Pediatric Asynchronous Telehealth Consultations

Secure app-based secondary healthcare clinical decision support to deployed forces in the UK Defence Medical Services

BACKGROUND

Modern instant messaging systems facilitate reach-back medical support for Defence Medical Services (DMS) by connecting deployed clinicians to remote specialists. The mobile app Pando (Forward Clinical, UK) has been used for this purpose by the DMS via the 'Ask Advice' function. We aimed to investigate the usage statistics for this technology in its first 1000 days to better understand its role in the DMS.

METHODS

An observational study was undertaken using metadata extracted from the prospective database within the application server for clinical queries between June 2019 and February 2022. These data included details regarding number and name of specialties, timings, active users per day and the number of conversations.

RESULTS

There were 29 specialties, with 298 specialist users and 553 requests for advice. The highest volume of requests were for trauma and orthopaedics (n=116; 21.0%), ear, nose and throat (n=67; 12.1%) and dermatology (n=50; 9.0%). There was a median of 164 (IQR 82-257) users logged in per day (range 2-697). The number of requests during each day correlated with the number of users on that day (r=0.221 (95% CI 0.159 to 0.281); p<0.001). There were more daily users on weekdays than weekends (215 (IQR 123-277) vs 88 (IQR 58-121), respectively; p<0.001). For the top 10 specialties, the median first response time was 9 (IQR 3-42) min and the median time to resolution was 105 (IQR 21-1086) min.

CONCLUSION

In the first 1000 days of secure app-based reach-back by the DMS there have been over 500 conversations, responded to within minutes by multiple specialists. This represents a maturing reach-back capability that may enhance the force multiplying effect of defence healthcare while minimising the deployed 'medical footprint'. Further discussions should address how this technology can be used to provide appropriately responsive clinical advice within DMS consultant job-planned time.

Applying a Military Teleophthalmology Mobile App in a Noncombat Emergent Care Setting

INTRODUCTION

Teleophthalmology has a natural role in the military due to the inherent organization of its medical system, which provides care to patients in remote locations around the world. Improving access to ophthalmic care enhances force readiness because ocular trauma and disease can cause vision impairment or blindness and can occur anywhere service members are located. Recently, a secure, Health Insurance Portability and Accountability Act-compliant mobile phone application (app) for teleophthalmology called Forward Operating Base Expert Telemedicine Resource Utilizing Mobile Application for Trauma (FOXTROT) was beta tested in Afghanistan and demonstrated that this solution can improve and extend ophthalmic care in a deployed environment. There are few civilian or military teleophthalmology solutions for ocular trauma and disease in an urgent or emergent ophthalmic care setting. Civilian teleophthalmology solutions have largely been developed for disease-specific models of care. In this work, we address this gap by testing the FOXTROT app in a non-deployed, emergent care setting.

MATERIALS AND METHODS

We evaluated the use of the teleophthalmology mobile phone app (FOXTROT) in a non-deployed military setting at the Malcolm Grow Medical Clinics and Surgery Center at Joint Base Andrews in Maryland. Consults from the emergent care center were placed by providers using the app, and the on-call ophthalmologist responded with treatment and management recommendations. The primary outcomes were response within the requested time, visual acuity tested in both eyes, agreement between the teleophthalmology and the final diagnosis, and the number of communication or technical errors that prevented the completion of consults. The secondary outcomes were average response time and the number of consults uploaded to the medical record.

RESULTS

From October 2020 to January 2022, 109 consults were received. Ten consults had communication or technical errors that prevented the completion of consults within the app and were excluded from the analysis of completed consults. Of the 99 completed consults, responses were given within the requested time in 95 (96.0%), with the average response time in 11 minutes 48 seconds (95% confidence interval, 8 minutes 57 seconds to 14 minutes 41 seconds). Visual acuity was tested in both eyes in 56 (56.6%). There was agreement between the teleophthalmology diagnosis and the final diagnosisin 40 of 50 (80.0%) consults with both a teleophthalmology and final diagnosis. Ninety-eight (99.0%) consults were uploaded to the patient's medical record.

CONCLUSIONS

Beta testing of a teleophthalmology mobile phone app (FOXTROT) in a noncombat emergent care setting demonstrated that this solution can extend ophthalmic care in this environment at a military treatment facility. However, improvements in the reliability of the platform are needed in future developments to reduce communication and technical errors.

Updated Review of the Pacific Asynchronous Telehealth System's Impact on Military Pediatric Teleconsultations

Introduction: The Pacific Asynchronous TeleHealth (PATH) system is an asynchronous provider-to-provider teleconsultation platform utilized by military medical facilities throughout the Western Pacific Region. This study focused on PATH utilization for pediatric cases and its impact on patient transfers and cost avoidance. Methods: This retrospective analysis reviewed PATH cases from March 2017 to February 2020 for patients aged 0-17 years. We reviewed the referring users' responses to survey questions related to the impact of PATH consultation on patient travel for in-person subspecialty care and the need for local referral. Data for cost avoidance were estimated using per diem rates and airline flight costs for Fiscal Year 2020. Results: A total of 2,448 pediatric consultations were submitted from 29 military medical facilities. Pediatric Pulmonology (n = 557, 24.5%), Pediatric Cardiology (n = 446, 19.6%), and Pediatric Neurology (n = 236, 10.37%) had the highest percentage of pediatric teleconsults. Approximately 42% of referring users completed the survey questions. Among survey respondents, 710 (69.4%) indicated that unnecessary patient transfers were prevented, equating to a cost savings of ∼$3.3 million. Conclusions: We observed robust utilization of the PATH system by pediatric providers in the Military Health System that ultimately resulted in substantial cost avoidance. This asynchronous telemedicine platform is a vital asset in locations with limited access or travel restriction to medical specialists, such as during pandemics.

Ongoing effects of eConsultation in nephrology on hospital referral rates: An observational study

INTRODUCTION

eConsultation in nephrology is an innovative way for general practitioners (GPs) to consult a nephrologist. Studies have shown that questions from GPs can be answered and intended referrals can be avoided by eConsultation. However, follow-up data are lacking. The primary aim of this study was therefore to assess whether patients for whom a referral to the outpatient clinic of a medical specialist was avoided in the short term were not then referred for the same problem within one year after the eConsultation.

METHODS

All eConsultations sent between June 2017 and April 2018 to seven nephrologists in three different hospitals in The Netherlands were included. Exclusion criteria were duplications and missing data on follow-up. Data were obtained from the eConsultation application forms and from GP medical records.

RESULTS

A total of 173 eConsultations were included. Of the 32 patients for whom a referral was initially prevented, 91% (95% confidence interval 75-98) had not been referred to a specialist for the same problem within one year after the eConsultation.

DISCUSSION

eConsultation in the field of nephrology can prevent referrals in the long term. It can therefore contribute to a more modern and efficient health-care system in which chronic care is provided by GPs in close proximity to patients, while specialist support is easily available and accessible through eConsultation when necessary.

Reduction in Medical Evacuations from Iraq and Syria Following Introduction of an Asynchronous Telehealth System

Introduction

While deployed, military medical personnel manage routine medical issues that fall under the category of Disease Non-Battle Injury (DNBI). The 86th Combat Support Hospital (CSH) partnered with Combined Joint Task Force-Operation Inherent Resolve (CJTF-OIR) Surgeon Cell, and Special Operations Joint Task Force-Operation Inherent Resolve (SOJTF-OIR) Surgeon Cell, to introduce the Health Experts onLine Portal (HELP) telemedicine system to medical personnel in Iraq and Syria. HELP is an asynchronous (store and forward) online system that provides secure provider-to-provider teleconsultation services for routine patient care and medical evacuation (MEDEVAC) coordination. The goal was to reduce the need for MEDEVAC by providing expert consultation to medical providers in farther-forward deployed units.

Material and Methods

In June 2017, the 86th CSH launched HELP telemedicine services for Kuwait. Following the successful implementation of the telemedicine system in Kuwait, the 86th CSH leadership partnered with CJTF-OIR and SOJTF-OIR medical leadership in launching the system within Iraq and Syria as well as making the system available to all deployed locations in Central Command (CENTCOM). This was a prospective cohort study designed to determine if having convenient and secure access to remote subspecialty consultation would be associated with a reduction in routine MEDEVACs from far forward in the battle space. In August 2017, new-user training was completed and the program launched in Iraq and Syria. This study analyzes the baseline MEDEVAC rate in 3 months before the implementation of HELP telemedicine compared to 3 months following the implementation.

Results

Iraq and Syria cases in the HELP telemedicine system accounted for 17.2% (76) of total CENTCOM telemedicine case volume over the 7-month study period. Comparing the 3-month period before and after implementation of HELP, use of asynchronous telemedicine in Iraq and Syria was associated with a reduction in total MEDEVACs from 157 to 68 (56.7% reduction, p &lt; 0.001). DNBI represented the majority of the change, (65.0% reduction, p &lt; 0.001). MEDEVAC for battle-related injuries decreased slightly from 13 to 6 per 3-month period (p = 0.03).

Conclusions

This is the first prospective study to demonstrate an association between the initiation of asynchronous telemedicine capabilities in a combat zone and decreased MEDEVACs. Annualized numbers would predict a reduction of 328 MEDEVACs/year for each 10,000 personnel by utilizing asynchronous telemedicine. This represents a significant potential cost savings of $1.2 million/year through avoidance of routine medical movement of personnel and supports unit readiness by retaining service members in areas of combat operations.

Comparison of a Novel Handheld Telehealth Device with Stand-Alone Examination Tools in a Clinic Setting

Background and Objective: Research demonstrates that telemedicine is effective in pediatric settings but little is published to validate the quality of the data acquired by remote peripheral examination devices to accurately inform clinical decision-making.Introduction: The primary aim was to compare a novel Food and Drug Administration (FDA)-cleared multifunctional remote examination device (Tyto) with other stand-alone digital examination devices. The secondary aim was to ascertain whether either device produced images or sounds better able to provide clinical information to clinicians caring for children.Materials and Methods: Otoscopic images and heart and lung sounds from 50 patients of ages 2-18 years were acquired using the novel device and a stand-alone digital otoscope and stethoscope. Data were stored on a secure server for review by physicians (two pulmonary faculty, two general faculty, two cardiology faculty, and two cardiology fellows). Reviewers were blinded and they reviewed images and audio files in a randomized manner. Images and sounds were scored in terms of quality using a Likert scale. Means and standard deviations (and t-tests to compare those means) were calculated. Individual (heart sounds, lung sounds, and otoscopic images) and aggregate scores were compared.Results: The novel device provided higher sound and image quality with less chance of an inability to make a diagnosis than the stand-alone devices. The novel device had a superior mean comparative diagnostic score with a high intra- and inter-reliability of cardiac, pulmonary, and otoscopic diagnosis.Discussion and Conclusions: The novel device outperformed the stand-alone digital stethoscope and otoscope and was better able to provide usable data to support a clinical encounter.

Barriers and facilitators for implementation of electronic consultations (eConsult) to enhance access to specialist care: a scoping review

INTRODUCTION

Electronic consultation (eConsult)-provider-to-provider electronic asynchronous exchanges of patient health information at a distance-is emerging as a potential tool to improve the interface between primary care providers and specialists. Despite growing evidence that eConsult has clinical benefits, it is not widely adopted. We investigated factors influencing the adoption and implementation of eConsult services.

METHODS

We applied established methods to guide the review, and the recently published Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews to report our findings. We searched five electronic databases and the grey literature for relevant studies. Two reviewers independently screened titles and full texts to identify studies that reported barriers to and/or facilitators of eConsult (asynchronous (store-and-forward) use of telemedicine to exchange patient health information between two providers (primary and secondary) at a distance using secure infrastructure). We extracted data on study characteristics and key barriers and facilitators were analysed thematically and classified using the Quadruple Aim framework taxonomy. No date or language restrictions were applied.

RESULTS

Among the 2579 publications retrieved, 130 studies met eligibility for the review. We identified and summarised key barriers to and facilitators of eConsult adoption and implementation across four domains: provider, patient, healthcare system and cost. Key barriers were increased workload for providers, privacy concerns and insufficient reimbursement for providers. Main facilitators were remote residence location, timely responses from specialists, utilisation of referral coordinators, addressing medicolegal concerns and incentives for providers to use eConsult.

CONCLUSION

There are multiple barriers to and facilitators of eConsult adoption across the domains of Quadruple Aim framework. Our findings will inform the development of practice tools to support the wider adoption and scalability of eConsult implementation.
